Description
Technical field
The present invention relates to building hoist technical field, more particularly to a kind of building hoist state feedback control system.
Background technology
Building hoist is widely used, but building hoist is being run as a kind of people, the dual-purpose vertical lifting equipment of goods
During, can be because of the brake apparatus of one of motor in the adhesion of brake contactor, external signal interference, transmission system
The reason such as abrasion or failure, causes equipment brake fault occur, or even can accidentally occur slipping cage phenomenon, and slipping cage can trigger
Anti-falling safety device, cause lift can not normal use.There is document to propose solution for this potential safety hazard, such as：In
State's patent：A kind of building hoist brake apparatus monitoring system, the patent No.：201420519497.3 it which disclose one kind
Building hoist brake apparatus control system, including control switch, controller, encoder, display screen, contracting brake mechanism and driver
Structure；Control switch produces command signal and transmitted to controller, and controller sends corresponding command signal control transmission mechanism and embraced
Brake mechanism；The input of encoder is connected with transmission mechanism, for gathering the displacement of lift, and the displacement of collection is anti-
It is fed to controller；Display screen is connected with controller, for the displacement of alarm indication lift.The invention can find to make in time
Dynamic system potential safety hazard.
But the building hoist brake apparatus monitoring system being previously mentioned in above-mentioned patent document, construction can only be lifted
Machine from start braking be monitored to the displacement stopped completely after, prompt operating personnel by alarm indication, and need people
Equipment is braked for operation control switch.Although above-mentioned patent document puts forward to potential safety hazard existing for building hoist
Solution, but still suffer from some defects：First, the whole service process not to building hoist is monitored in real time, two
It is that brake measure can not be taken to building hoist in time.There is presently no the means of effect to building hoist in the process of running
Potential safety hazard carry out in real time monitor and brake measure is taken to building hoist in time.
The content of the invention
In order to solve brake fault that building hoist occurs in the process of running and contingency to slip safety caused by cage hidden
Suffer from problem, present invention particularly provides a kind of building hoist state feedback control system.
The technical solution used in the present invention is as follows：
A kind of building hoist state feedback control system, it is characterized in that：Including operation handle, state feedback controller, frequency conversion

Input is connected with transmission mechanism, for gathering the speed of lift operation, and by the velocity feedback collected to feedback of status
Controller；State feedback controller sends corresponding instruction control frequency converter and transmission mechanism；Display and STATE FEEDBACK CONTROL
Device is connected, the speed of display lift operation.
Described state feedback controller is single by MCU micro control units, gear collecting unit, encoder collecting unit, driving
Member and power supply composition.
Described gear collecting unit is used for collecting electric signal caused by operation handle, and packs for ease of MCU micro-control lists
The data frame format that member receives, is transferred to MCU micro control units.
Described encoder collecting unit is used for collecting the velocity information of the lift operation of encoder feedback, and is packaged as
The data frame format for being easy to MCU micro control units to receive, is transferred to MCU micro control units.
Described MCU micro control units receive the information of gear collecting unit and the transmission of encoder collecting unit, pass through inside
Logical operation, contrasted with setting value, operational order is transferred to driver element.
For described driver element according to the operational order of MCU micro control units, driving frequency converter is out of service, drives driver
Structure skidding.
Beneficial effects of the present invention are：
By the lift gear information and velocity information that will be collected, compared with setting value, building hoist can transported
Row state is monitored in real time, is found potential safety hazard in time and is taken brake measure to building hoist, prevents contingency
Occur.
